Abstract
The utility model relates to an improved omni-fabric lining which is suitable to the lining fabrication and reconstruction of the external heating salt-bath resistance furnaces, the moderate temperature well resistance furnaces, the well drawing electrical resistance furnaces and a part of box resistance furnaces in the heat treatment industry. This lining is composed of the fibrofelt, bearing bricks, resistance wires and fixed metal pieces. The utility model is characterized in that the lining is compressed for three times, and it only compresses one phase lining each time, and then the three-phase lining is fixed into an integration by using a compressing plate screw, therefore, providing an omni-fabric lining which is reasonably structured, novel and firm, simple to construct, has high efficiency and can ensure the production safety.
Description
The utility model relates to a kind of improved full aluminosilicate refractory fiber resistance furnace lining, is suitable for the manufacturing and the transformation of external-heat salt bath resistance furnace, middle hot-well formula resistance furnace, pit type tempering resistance furnace and the part chamber type electric resistance furnace furnace lining of mechanical system heat treatment industry.
Aluminosilicate refractory fiber is nineteen forty-one to cling to the cloth cock by the U.S.---Joe Wilcox (Babcock Wilcox) company finds that common refractory fibre has been made with the air blown method first by nineteen forty-two B﹠W company when fusion kaolin.Owing to cost an arm and a leg, the scope of application was very limited at that time.Because aluminosilicate refractory fiber is an energy-saving material preferably, in recent years, at home and abroad under the energy scarcity situation, uses the aluminosilicate refractory fiber transformation and make the resistor furnace for heat treatment furnace lining and saved the energy effectively.Up to the present, the reasonable resistance furnace of power savings is the furnace lining that adopts the soft felt of full fiber to make, and according to the data introduction, this resistance furnace is compared with traditional refractory brick furnace lining resistance furnace, and electric energy reaches 40%.Its furnace lining by the soft felt of fiber, resistance wire, put brick and the metalwork that is used for fixing fibrofelt, resistance wire and puts brick is formed.Having pointed out in " domestic and international application refractory fibre aspect make electric furnace creationary success experience " book that entire fibre lining was made in present stage remains in weak point, can conclude the following aspects: overall structure is poor, the easy short circuit of heating, weather-proof property are poor, complex process, make trouble, the cost height.Its reason is that the metal fixing of furnace lining partly is exposed in the high-temperature burner hearth, metalwork is made with the valuable heat resisting steel of complex structure, furnace lining fibrofelt fixed form makes machine direction parallel with furnace lining inner surface and airflow direction, and when the fiber that is exposed to high temperature side shrank, restrained force was less between the fiber, make fibre shedding easily, the weather-proof ability of fiber is also poor, causes fiber early to damage, and has influenced the furnace lining overall construction intensity, resistance wire is exposed in the burner hearth, easily causes short circuit.
In order to solve the problem of above-mentioned existence, task of the present utility model provide a kind of rational in infrastructure, novel, firm, construction is simple, cost is low, efficient is high, and can guarantee the soft felt furnace lining of full fiber of production safety, this furnace lining is applicable to the manufacturing and the transformation of the external-heat salt bath resistance furnace of heat treatment industry, middle hot-well formula resistance furnace, pit type tempering resistance furnace and part chamber type electric resistance furnace furnace lining.
The utility model is achieved in that furnace lining divides three compactings, suppresses a phase furnace lining at every turn, with plate screw the three-phase furnace lining is fixed into one then.With the complicated valuable heating resisting metal fixture of general carbon steel screw substitute structure.Furnace lining of the present utility model is carried out the result of quality inspection and Performance Detection, prove that this furnace lining good airproof performance, overall structure are strong, the electric heating element fixation, and can guarantee production safety, easy construction, economical rationality, furnace lining of the present utility model is compared with hard fibre tile stove lining, electric energy reaches 58%, enhances productivity 47%.
The concrete structure of this utility model will be described in further detail in conjunction with the accompanying drawings.
Accompanying drawing is to use the longitudinal sectional drawing of a resistance furnace of this utility model furnace lining.
This utility model furnace lining by fibrofelt (4), put brick (2), resistance wire (1) and fixing metal spare and form.It is characterized in that fibrofelt (4) is cut into required form, (and the pressure stubble that staggers) stacks successively, and resistance wire is put brick (2) be pressed into a phase furnace lining by the size of burner hearth layering with follower bolt (3), take turns doing the three-phase furnace lining, use follower bolt (5) that the three-phase furnace lining is fixed into one then.Three property compacting furnace linings have solved effectively puts brick (2) spacing uneven phenomenon.When the compacting furnace lining, put brick (2) up and down between distance more smaller than good resistance wire (1) external diameter of design coiling, this is because the soft felt of fiber (4) high resilience, and resistance wire (1) being stuck in tightly put between the brick (2), makes resistance wire (1) be unlikely to cause easily short circuit and damage.Resistance wire (1) is the helical form electric heating element of OCr25Al5 material, and resistance wire diameter and coiling size can be determined according to stove watt level and actual conditions.Put brick (2) and be used for fixing resistance wire (1), bolt (3) and (5) are general carbon steel materials, because bolt (3) inserts fibrofelt (4) inside, be not exposed in the burner hearth, fiber temperature is lower on every side for bolt (3), fiber (4) plays the secluding air effect simultaneously, so but be difficult for the just complicated valuable heating resisting metal fixture of substitute structure of oxidation.For furnace lining of the present utility model, its fibrofelt fixed form makes machine direction vertical with furnace lining surface and airflow direction, the fiber that only is exposed to high temperature one side in the fire-retardent fiber felt-rug (4) shrinks, the fiber Yin Wendu of remainder is lower, it is less to shrink or do not shrink, thereby hindered the contraction of temperature end fiber, because restrained force is bigger between the fiber, the fiber difficult drop-off, weather-proof property might as well.Therefore, it is little that the fibrofelt of the utility model furnace lining has shrinkage, is out of shape little and the high advantage of intensity.
Claims (1)
1, a kind of improved full aluminosilicate refractory fiber furnace lining, it is made up of fibrofelt (4), the metalwork putting brick (2), resistance wire (1) and anchoring fiber felt (4), resistance wire (1) and put brick (2), it is characterized in that follower bolt pass the fire-retardent fiber felt-rug of lamination (4) with resistance wire (1), put brick (2) and be fixed as a phase furnace lining, the three-phase furnace lining is by follower bolt (5) three one phase furnace linings fixedly to be formed, and puts the brick spacing and is slightly less than the resistance wire external diameter.
